I’m not to sure about this
Diffraction occurs when a wave moves through an opening in a barrier. This causes the wave to change direction and spread out.
Waves can behave in three different ways depending on the obstacles they encounter. They can reflect, refract or diffract. In diffraction, waves such as sound, light or water either bend around small objects that obstruct their passage or spread out as they travel through a gap in the barrier.
The degree of diffraction forms a direct relationship with wavelength. It generally increases as wavelength increases. Conversely, the amount of bending lessens as wavelength decreases. However, if the opening of the barrier is smaller than the wavelength, the effect of diffraction is not easily observed. Hope this helps.
The correct answer for this question is: "<span>B) kidneys clean the blood by filtering it to remove wastes." Kidneys clean the blood by filtering it and removing the waste.
The correct answer for this question is: "</span><span>A) secretes excess water as sweat." The role of the skin in the excretory system is to secrete waste and excess water as sweat.</span>
D Bc I just did it and got it right
Not a lot besides the fact that they are both mixtures in water, because a solution is a mixture in which the solutes ( solids) dissolve, and suspension is a mixture in which the solutes don't dissolve.
